Why is my printer a bit inaccurate around the center of the build-plate?
If you are experiencing inaccuracies when you’re printing at the center of the build-plate, the reason could be that the calibration of the arm (the Y-axis) isn’t quite accurate. You can test this by going to “Printing tools” in the app and start the Y-calibration. After having printed the “Y test”, please measure the length of it (it’s important that you use a very precise measuring device, e.g. a vernier caliper) and type in the length of the test print to end calibration.
